摘　　要：介绍一种既适合于中性点不接地电网，又适合于中性点经消弧线圈并电阻（或串电阻）接地电网（又称补偿电网）的接地选线保护，该选线保护装置解决了现有接地选线保护不能适应中性点经消弧线圈并电阻接地电网的问题．A ground fault protection is introduced which is not only suitable for unground neutral network, but also suitable for earth neutral system (also called compensation network) which grounding through arcextinguishing coil connected with a parallel resistance (or in serial). This protection device solves the problem of existing ground protection not suitable for earth neutral system which grounding through arcextinguishing coil connected with a parallel resistance.
